An analytical solution for the displacement field and corresponding stress state in multi-layer cylinders subjected to pressure and thermal loading is developed.
Two independent sets of analytical solutions have been derived for calculation of displacements and stresses in elastic multi-layer cylinders subjected to both pressure and thermal loading.
The purpose of this research paper is to report on the diffusion impedance of multi-layer cylinders.
In this model, casing, cement sheath and surrounding rocks were seen as multi-layer cylinders and were analyzed based on thermoelastic, elastoplastic and poroelastic theory, respectively.
Numerical results for the scattering form function and noise reduction of a two-layer infinite cylinder are given to illustrate the effect of layer material characteristics, variation of thickness of either of the constituent layers, cylinder dimensions, and ambient media.
Examples of a homogeneous PZT-4 cylinder and a two-layer cylinder composed of a PZT-4 material at crystal orientations of ±30° with the longitudinal axis are presented.
Some Lamb waves in a plate and some circumferential waves in a one-layer cylinder are characterized by the resonance frequencies where the group velocity is vanishing while the phase velocity remains finite.
The layered cylinder model used multipole expansions to simulate ultrasonic scattering from mammary ducts represented as three-dimensional cylinders with an epithelial cell layer and interior lumen, and was similar to a model used to simulate elastic wave scattering from normal and clotted blood vessels [ 44].
By introducing two recursive algorithms, the extrusion stresses between two neighbor layers in the multi-layered cylinder submitted to uniform pressures on the inner and outer surfaces can be simply determined.
Analytical expressions of the diffusion impedance in multi-layer solid cylinders (sorption/desorption experiments) and through multi-layer hollow cylinders (permeation experiments) have been obtained by integration of Fick's diffusion equation in cylindrical coordinates.
Without the rubbery polymer layer, the cylinder blocks some of the light diffusing through the liquid and casts a shadow.
